Cryptographically weak CSRF tokens in Apache MyFaces
Résumé
Cryptographically weak CSRF tokens in Apache MyFaces
Description d'origine
La description telle que publiée par la source (souvent en anglais).
In the default configuration, Apache MyFaces Core versions 2.2.0 to 2.2.13, 2.3.0 to 2.3.7, 2.3-next-M1 to 2.3-next-M4, and 3.0.0-RC1 use cryptographically weak implicit and explicit cross-site request forgery (CSRF) tokens. Due to that limitation, it is possible (although difficult) for an attacker to calculate a future CSRF token value and to use that value to trick a user into executing unwanted actions on an application.
Mitigation:
Existing web.xml configuration parameters can be used to direct
MyFaces to use SecureRandom for CSRF token generation:
org.apache.myfaces.RANDOM_KEY_IN_VIEW_STATE_SESSION_TOKEN=secureRandom
org.apache.myfaces.RANDOM_KEY_IN_CSRF_SESSION_TOKEN=secureRandom
org.apache.myfaces.RANDOM_KEY_IN_WEBSOCKET_SESSION_TOKEN=secureRandom
